iOS Present Popover from bar button item bottom

I have an UIPopoverController that presents an UIViewController using this method:

[self.popover presentPopoverFromBarButtonItem:self.infoBarButtonItem 
                     permittedArrowDirections:UIPopoverArrowDirectionUp
                                     animated:YES];

self.popover is my UIPopoverController.

The code works well, but the Popover arrow is in the middle of the BarButtonItem how do I display the Popover with its arrow "under" the button?

This is what it currently looks like:

How about this

UIBarButtonItem *item = self.infoBarButtonItem ;

UIView *view = [item valueForKey:@"view"];

if(view){

        CGRect frame=view.frame;

        [self.popover presentPopoverFromRect:frame
                                      inView:view.superview
                    permittedArrowDirections:UIPopoverArrowDirectionUp
                                    animated:YES];
